Internal & External Spurs & Helical
Spur Gears
Spur gears need teeth to be cut parallel to the gear axis and an involute, or specific curved profile, that ensures smooth, predictable load transfer. Helical gears bring a new angle to the tooth form. For Milan’s this is from 1 to 45 degrees, which distributes the load across more tooth surface. This brings a quieter operation and greater load-carrying capacity. Many times, this is the preferred choice for customers where drive applications need low noise, consistent smoothness and high durability.
Internal Spur Gears
Internal spur gears, where the teeth are cut on the inside of a ring or bore, requires specialized tooling and setup that Milan’s specializes in. These types of internal spur gears are regularly done, as our operators understand the critical operations between tooth form, spacing, and finish that controls the performance of the gear.

External Spur Gears
Spur gears are the most common external gear form, with teeth cut parallel to the gear axis and an involute tooth profile that ensures smooth, predictable load transfer. Milan's Machining cuts external spur gears spanning 2.5 to 32 Diametral Pitch and outside diameters up to 72 inches, holding the tooth form and spacing tolerances that consistent, reliable gear performance demands.
Helical Gears
Helical gears introduce an angle to the tooth form — at Milan's Machining, from 1 to 45 degrees — which distributes the load across more tooth surface simultaneously. The result is quieter operation and greater load-carrying capacity than a standard spur gear, making helical gears the preferred choice in drive applications where low noise, consistent smoothness, and high durability are the priority. Milan's Machining cuts helical gears spanning 2.5 to 32 Diametral Pitch and outside diameters up to 72 inches, holding the precise tooth form geometry these demanding applications require.
